This is Logic before he was turned into a draconequus. Though his cutie mark isn't a shield but a capital 'A' with a plus sign. His special talent is working with foals with behavioural problems. He has a sister but their parents aren't in the picture.

As a foal, he lived in fear of his father and his mother was never around, and when she was she made his life a living hell. He didn't get his cutie mark until well into adulthood (when he turned twenty four) and he was always made fun of for it. Up until his giant change (within two months of his cutie mark, cruel irony), he'd been working on going into college. He had a few good friends and that was enough for him. He lives in Ponyville, though he was originally from Manehatten.

Also, I forgot that he was an Appaloosa, so he's got a pink butt.
